ABSTRACT

OBJECTIVE: To estimate trends in maternal opioid use disorder (OUD) and neonatal abstinence syndrome (NAS) in Maine using the most recent data available.

STUDY DESIGN: We used hospital discharge data to estimate the annual prevalence of maternal OUD and NAS between 2016 and 2022. In addition, we used birth certificate-linked Medicaid data to estimate related trends among Medicaid enrollees.

RESULT: From 2016 to 2022, the prevalence of maternal OUD decreased from 35.3 to 18.8 per 1000 deliveries and the prevalence of NAS decreased from 33.2 to 14.0 per 1000 newborns (linear trend p values <0.01). Decreasing trends were also found among Medicaid enrollees.

CONCLUSION: In Maine between 2016 and 2022, there was a decrease in maternal OUD and NAS diagnoses recorded in administrative datasets. These findings should be interpreted with caution due to changes in how OUD and NAS diagnoses are recorded and COVID-related changes in healthcare utilization.
